BACKGROUND OF THE INVENTION

Currently, in the technical fields of video shooting, photo taking and/or surveillance and so on, a carrier loaded with a video camera or a still camera, for example, an aircraft, a car, a ship, a robot and a human body and so on, inherently has high frequency vibration and low frequency vibration, and thus needs to be configured with a stable self-balancing gimbal used to be loaded with the video camera, the still camera etc. to achieve stable shooting. Meanwhile, the gimbal is widely used for entertainments and model airplane video shooting and so on. Excellent photos and/or videos in various directions may be shot by utilizing a plurality of keypads or remote controller to wirelessly control lenses of cameras to perform directional actions such as a rotation, a pitch and so on. The gimbal may be used to support such optical devices such as a video camera, a still camera, a telescope, a remote video camera and a measuring instrument and so on. According to operations of these optical devices, it is necessary for the gimbal to have stable support function and be easy to control and adjust directions of the optical device. A dynamic self-balancing gyroscopic biaxial or triaxial gimbal may achieve such fixation, support and orientation action.

In one prior art technique, the gimbal may shoot videos and/or photos in various directions by using a plurality of keypads or a remote controller to wirelessly control the optical devices to perform directional actions such as rotation and pitch. With the solution utilizing keypads and remote controller wirelessly, the angle in pitch and/or rotation direction may be controlled through a plurality of keypads, causing a bad hand feeling and low accuracy in performing actions. In addition, a receiver is required because the remote controller is operated wirelessly, so that it is inconvenient to operate, and under certain circumstances, for example, in case of a handheld remote controller, the gimbal needs to be operated by several persons at the same time.

DETAILED DESCRIPTION OF THE INVENTION

For a clear understanding of the technical features, objects and advantages of the invention, specific embodiments of the invention will now be explained in detail in conjunction with the accompanying drawings.

According to embodiments of the invention, a gimbal is provided, which may be loaded with an optical device thereon, for example, a video camera, a still camera, a telescope, a remote video camera, a measuring instrument and so on. The gimbal may be configured for fixing the optical device and optionally adjusting an attitude of the optical device (for example, change a height, an inclination angle, a shooting direction of the optical device and/or keep the optical device stable in a determined attitude) in order to obtain high quality videos and/or photos and so on.

As shown in FIGS. 1 to 4, an embodiment of the invention provides a gimbal 100 configured to be loaded with an optical device, to control the optical device to perform actions, and to implement actions of the optical device such as pitch and/or rotation. The gimbal 100 may comprise a controlling device 1, a controlling assembly 2 connected with the controlling device 1, and a performing assembly 3 connected with the controlling assembly 2. In some embodiments, the controlling assembly 2 may be disposed between the controlling device 1 and the performing assembly 3.

In some embodiments, the controlling device 1 may comprise a rocker 11 configured for receiving an action instruction sent by a user and generating a control instruction to be sent to the controlling assembly 2. The rocker 11 may comprise a rocker handle 12 as well as a potentiometer assembly 13 and a keypad 14 respectively connected with the rocker handle 12.

In some embodiments, the rocker handle 12 may be movable along an up direction A1, along a down direction A2, along a left direction B1, along a right direction B2 and along a press direction C.

In some embodiments, the potentiometer assembly 13 may comprise a first potentiometer 131 configured for controlling a pitch action of the optical device and a second potentiometer 132 configured for controlling a rotation action of the optical device.

In some embodiments, the keypad 14 may be configured for switching operating modes of the gimbal 100 which may comprise a follow mode and a locked mode. In the follow mode, not only a swing caused during the movement of the gimbal 100 may be filtered out, but also the shooting direction of the optical device may follow up with the moving direction of the gimbal 100. In the locked mode, the shooting direction of the optical device may be already locked in a specified direction (for example, an initial direction of the optical device), regardless of how the gimbal 100 moves. Both of the above two modes may be suitable for a single person to shoot with the optical device and control the direction of the optical device at the same time.

In some instances, the controlling assembly 2 may be connected with the controlling device 1, and may be configured for generating, based on a control instruction sent by the controlling device 1, a performing instruction for implementing a corresponding action, and sending the performing instruction to the performing assembly 3.

In some instances, the performing assembly 3 may be configured for implementing an action control for the optical device according to the performing instruction.

Further, the controlling device 1 may also comprise a support arm 15 for supporting the rocker 11, and a bracket 16 located on an end of the support arm 15. The support arm 15 may be in a hollow bucket shape.

In some instances, the performing assembly 3 may comprise a first rotation member 304, a second rotation member 306 rotatably connected with the first rotation member 304, a carrying member 308 connected with the second rotation member 306, a first motor 301 for driving the second rotation member 306 to rotate relative to the first rotation member 304, and a second motor 302 for driving the carrying member 308 to rotate relative to the second rotation member 306. The optical device may be loaded on the carrying member 308. The first motor 301 may drive the second rotation member 306 to rotate relative to the first rotation member 304, therefore enabling the optical device loaded on the carrying member 308 to perform a pitch action; the second motor 302 may drive the carrying member 308 to rotate relative to the second rotation member 306, therefore enabling the optical device loaded on the carrying member 308 to perform a rotation action (i.e. an action of leftward or rightward tilt).

Further, in some embodiments, by controlling the rocker handle 12 in the controlling device 1, a user may send the rocker 11 six kinds of action instructions which are respectively: a short press action instruction, a long press action instruction, a push-up action instruction, a push-down action instruction, a push-left action instruction and a push-right action instruction. In some embodiments, the short press action instruction may mean that the user may press the rocker handle 12 along the press direction C for a short time when the rocker handle 12 is in the middle position of the rocker 11; the long press action instruction may mean that the user may press the rocker handle 12 along the press direction C for a long time when the rocker handle 12 is in a non-middle position of the rocker 11. In some embodiments, the “short time” may be less than 3 seconds; and the “long time” may be longer than 3 seconds. Of course, the duration of the “short time” and “long time” may be adjusted according to actual requirements. With regard to the middle position of the rocker 11, the push-up action instruction may mean that the user may push the rocker handle 12 along the up direction A1; the push-down action instruction may mean that the user may push the rocker handle 12 along the down direction A2; the push-left action instruction may mean that the user may push the rocker handle 12 along the left direction B1; and the push-right action instruction may mean that the user may push the rocker handle 12 along the right direction B2.

In some embodiments, the gimbal 100 may have two operating modes comprising a follow mode and a locked model. For example, when the gimbal 100 is in the follow mode, if the user sends the short press action instruction to the rocker 11, the operating mode of the gimbal 100 may be switched to the locked mode. Alternatively, when the gimbal 100 is in the locked mode, if the user sends the short press action instruction to the rocker 11, the operating mode of the gimbal 100 may be switched to the follow mode.

When the rocker handle 12 is in a non-middle position, if the user sends the long press action instruction to the rocker 11, the rocker handle 12 may return to the middle position.

In addition, when the rocker handle 12 is in the middle position, the first motor 301 and the second motor 302 may be in a stationary state but powered so as to hold torque.

Technical solutions that the controlling assembly 2 receives control instructions and sends performing instructions are well known in the present industry and will not be described herein.

In some instances, as the user sends the push-down action instruction to the rocker 11, the rocker handle 12 may contact with the first potentiometer 131, and the rocker handle 12 sends the look-down control instruction to the controlling assembly 2 via the first potentiometer 131; the controlling assembly 2, after receiving the look-down control instruction, may generate the look-down performing instruction for enabling the gimbal 100 to perform a look-down action, and send the look-down performing instruction to the performing assembly 3; the performing assembly 3, after receiving the look-down performing instruction, may control the gimbal 100 to perform the look-down action, that is, the first motor 301 may drive the second rotation member 306 to rotate counterclockwise relative to the first rotation member 304, therefore enabling the optical device loaded on the carrying member 308 to implement the corresponding look-down action to obtain videos and/or photos at corresponding more suitable angle of view and so on.

In some instances, as the user sends the push-left action instruction to the rocker 11, the rocker handle 12 may contact with the second potentiometer 132, and the rocker handle 12 may send the leftward-tilt control instruction to the controlling assembly 2 via the second potentiometer 132; the controlling assembly 2, after receiving the leftward-tilt control instruction, may generate the leftward-tilt performing instruction for enabling the gimbal 100 to perform a leftward-tilt action, and send the leftward-tilt performing instruction to the performing assembly 3; the performing assembly 3, after receiving the leftward-tilt performing instruction, may control the gimbal 100 to perform the leftward-tilt action, that is, the second motor 302 may drive the carrying member 308 to rotate clockwise relative to the second rotation member 306, therefore enabling the optical device loaded on the carrying member 308 to implement the corresponding leftward-tilt action to obtain videos and/or photos at corresponding more suitable angle of view and so on.

In some instances, as the user sends the push-right action instruction to the rocker 11, the rocker handle 12 may contact with the second potentiometer 132, and the rocker handle 12 may send the rightward-tilt control instruction to the controlling assembly 2 via the second potentiometer 132; the controlling assembly 2, after receiving the rightward-tilt control instruction, may generate the rightward-tilt performing instruction for enabling the gimbal 100 to perform a rightward-tilt action, and send the rightward-tilt performing instruction to the performing assembly 3; the performing assembly 3, after receiving the rightward-tilt performing instruction, may control the gimbal 100 to perform the rightward-tilt action, that is, the second motor 302 may drive the carrying member 308 to rotate towards the right relative to the second rotation member 306, therefore enabling the optical device loaded on the carrying member 308 to implement the corresponding action of rotating towards the right to obtain videos and/or photos at corresponding more suitable angle of view and so on.

In some instances, when the rocker handle 12 is in the middle position and the user sends the short press action instruction to the rocker 11, the rocker handle 12 may contact with the keypad 14, and the rocker handle 12 may send the switch control instruction to the controlling assembly 2 via the keypad 14. The controlling assembly 2, after receiving the switch control instruction, may generate the switch performing instruction for enabling the gimbal 100 to perform operating mode switch, and send the switch performing instruction to the performing assembly 3. The performing assembly 3, after receiving the switch performing instruction, may switch operating mode of the gimbal 100. For example, when the gimbal 100 is in the follow mode, if the user sends the short press action instruction to the rocker 11, the operating mode of the gimbal 100 may be switched to the locked mode. Alternatively, in some embodiments, when the gimbal 100 is in the locked mode, if the user sends the short press action instruction to the rocker 11, the operating mode of the gimbal 100 may be switched to the follow mode.

In some instances, when the rocker handle 12 is held in the position towards the up direction A1 or the down direction A2 from the middle position, if the user sends the long press action instruction to the rocker 11, the rocker handle 12 presses the first potentiometer 131 for a long time, and the rocker handle 12 may send the back-to-middle control instruction to the controlling assembly 2 via the first potentiometer 131. The controlling assembly 2, after receiving the back-to-middle control instruction, may generate the hold performing instruction for enabling the gimbal 100 to hold the current attitude, and send the hold performing instruction to the preforming assembly 3.
